They’re nice Amp that was acquired from the liquidation of a studio here in Nashville. Amp sounds fantastic. Only issue is the power switch won’t turn off the unit. It was powered on and off by a power strip. Other than that very nice amp. Please be photos for a better idea of condition. Shipping price is for lower 48 states.

This eBay item is a Crown DC-300A solid state stereo amplifier. It shows signs of use, not excessive. The rackmount bolt holes show use and wear. There are minor scratches on the knobs and panels, again not excessive. I tested it and both channels worked. There are LEDs on the front panel which may be overload indicators. I could not find a manual that explains them.Most of the DC-300A amps that Ive seen do not have these LEDs. One of the two LEDs blinks on at medium volume but I couldnt find any other indication of any overload. The audio was perfect on both channels. I think the problem is in the indicator, not in the amplifier. If I could find a schematic that included these LEDs I might be able able to find and fix the problem. I could not find a schematic that included these LEDs. If you want more info or more pictures please message me.
